DESCRIPTION

This manpage is a place holder until something better is written when
the netscript itself has stopped changing rapidly.
Please see the README file in the /etc/netscript directory, and READ
the configuration files if you need to change them. Apart from
network.conf, all of them contain sh (1) shell script functions which
are there so that various things can be altered or hooked in at the
right place. Network.conf contains the full network setup details,
including special interface setup for the likes of
ciped/pppd/wanconfig, and is fully commented with examples given.

UPGRADEPATHFROMKERNEL2.2.X

The firewall/IP filtering stuff in ipfilter.conf is the part that
changed radically with the move to iptables and a far better way of
setting up the IP filtering rules, however the QoS and interface
startup/shutdown in if.conf have changed but are backwards compatible
with the old 2.2.x ipchains version of netscript for the interface
address configuration settings. You will have to set up the filtering
again to use iptables by directly using the iptables commands.
Also, the kernel 2.2.x version scripts are set up so that iptables is
only run on a 2.4.x kernel, otherwise IP forwarding is disabled if
beforehand you set IPFWDING_KERNEL to FILTER_ON in network.conf.
This means that when you upgrade a box to a 2.4.x router kernel, you
should then be able to reboot it and log into remotely and upgrade
netscript to the version that will support 2.4.x. In this situation,
if you have set old IPFWDING_KERNEL setting to FILTER_ON beforehand in
network.conf, all IP forwarding through the box will also be disabled.
This means that you can safely remotely upgrade a firewall.
